The cost of a Notary Deed
In the vast majority of cases, the amount of taxes which the Notary pays to the Treasury on behalf of the customer represents more than half of the cost of the deed for the parties.
Save for the cases in which the value of the deed cannot be objectively determined, basically, the cost of the deed is proportional to the value of the operation, as both the applicable taxes and the other duties and contributions which the Notary is obliged to pay for various reasons are almost always proportional.
